Typo Products, backed by Ryan Seacrest, recently unveiled its first iPhone keyboard case, which is due to ship this month for $99. The product is a complete case, but it covers the bottom part of an iPhone 5 or 5S with a physical keyboard, which connects via Bluetooth. Overall, the accessory looks very interesting.

However, BlackBerry today announced a lawsuit against the company behind the case.

“This is a blatant infringement against BlackBerry’s iconic keyboard, and we will vigorously protect our intellectual property against any company that attempts to copy our unique design,” BlackBerry said in a statement.

BlackBerry holds various design and engineering patents on this type of keyboard, and it has used these patents in the past to keep competing products out of certain markets. The Typo case does resemble a BlackBerry keyboard in some ways, though this particular lawsuit feels like a dying company grasping at any option it can find to make some money or to maintain an advantage in the market.
